Emma Dorcus Tower of Westmorland Co NB

I have a Emma Dorcus Tower, born New Brunswick in 1850. She married a Charles H Allen. She and Charles adopted an Emma M Atkinson in the late 1890s. Emma M was the natural daughter of Frederic and Nettie F (Outhouse) Atkinson, married in Westmorland NB in 1887. Emma M was adopted by Charles H and Emma Dorcus (Tower) Allen. Nettie had a younger sister Agnes born 1881 who married Albion Niles. Agnes and Albion adopted an Evelyn, the natural daughter of Emma M (Atkinson/Allen) Hollingshead.

I realize that the Tower, Atkinson and Outhouse families are long standing in Westmorland. I have the parents of Nettie and Agnes as Benjamin and Sarah Jane Outhouse. For Frederic, born about 1864, I only have his widowed mother Fannie and siblings Charles and Albert. I have nothing on the direct family of Emma Dorcus Tower.

I would like to determine 1) The parents and siblings of Emma Dorcus Tower born Westmorland 1850.

2) Any possible relationship between the Tower and Outhouse/Atkinson familes.
